Radix Sort is a non-comparative sorting algorithm with asymptotic complexity O(nd). It is one of the most efficient and fastest linear sorting algorithms. Radix sort was developed to
Pointers are variables that contain the memory address of another variable. It enables the programmer to directly access the memory location and hence the value stored at it.
Counting Sort is a linear sorting algorithm with asymptotic complexity O(n+k), which was found by Harold Seward in 1954. Counting Sort is very time efficient and stable algorithm
